Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from the PowerPC port with all the Open Firmware bits removed and replaced by their EFI counterparts. On the whole, I think I prefer Open Firmware. This code is supposed to be an immutable shim that sits on the EFI system partition, loads /boot/loader.efi from UFS and tells the real loader what disk/partition to look at. It finds the UFS root partition by the somewhat braindead approach of picking the first UFS partition it can find. Better approaches are called for, but this works for now. This shim loader will also be useful for secure boot in the future, which will require some rearchitecture.

Eliminate last vestigies of NO_MAN= in the tree. Also, remove ineffectual NOMAN= lines. These don't change the build at all.

Move the efi loaders to be under sys/boot/efi. This will help us add support for booting arm and arm64 from UEFI. Differential Revision: https://reviews.freebsd.org/D2164 Reviewed by: emaste, imp (previous version) Sponsored by: The FreeBSD Foundation

Add generation of an EFI filesystem to hold boot1.efi. This is a near-exact copy of the code from boot1.chrp again. The resulting image is installed to /boot/boot1.efifat. If dd'ed to an 800K "efi" partition, it should result in a bootable system.

Use explicit --output-target to set EFI file format According to objcopy(1) --target is for use where the input and output formats are the same ("no translation"). In practice it does detect the input format in any case, but be explicit that we're specifying the output format as we are translating from ELF to EFI PE format. Sponsored by: The FreeBSD Foundation

Apparently some of the i386 boot blocks are so close to full that adding single lines to ufsread.c spills them over. Duplicate a whole bunch of code to get file sizes into boot1.efi/boot1.c rather than modifying ufsread.c.
